Extension trait for Vec<T> providing panic-safe access operations

Required Methods

fn pop_or_cbkp_error( &mut self, code: ErrorCode, message: impl Into<String>, ) -> Result<T, Error>

Pop from vector safely, returning a structured error if empty

Errors

Returns the specified error code and message if the vector is empty.

fn last_or_cbkp_error( &self, code: ErrorCode, message: impl Into<String>, ) -> Result<&T, Error>

Get last element safely, returning a structured error if empty

Errors

Returns the specified error code and message if the vector is empty.

fn last_mut_or_cbkp_error( &mut self, code: ErrorCode, message: impl Into<String>, ) -> Result<&mut T, Error>

Get last mutable element safely, returning a structured error if empty

Errors

Returns the specified error code and message if the vector is empty.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
